Research on the over-voltage of 220kV power system caused by traction transformer's commissioning


The over-voltage of 220kV power system appeared during the commissioning of several traction transformers in Jilin Province. Analysis showed that the electromagnetic oscillating of the system caused the over-voltage of the feeding phases. After setting up an accurate simulating model used in ATP-EMTP, the adverse influence on the electric power system and… (More)
